Using the correct method of scanning the items will never fail and gets what you want. 'IndexOf' will return -1 if no items are found which is why it fails.

THe code I posted shows one way to do this without error. You have to use an integer to select the correct item. You cannot easily use the 'index' of the array to check the boxes.

It can also come from setting the options on the CheckedListBox improperly. The issue is that you have not understood how a CheckedListBox works. Good times.Īgain, thanks for the information, it helps confirm that I'm not going crazy.Ok, too late for that. It reminds me of the c compilers back in the late 70s. I have run in to many weird things like this that turn out to be some code in an entirely different location to produce errors like this. The idea (which may or may not be a good one) is that if the first item (i0) is checked then the loop should set all the other items (i1 to i -1) to checked. When the error says, 'index = -1, and I clearly enter in an index of 1, then this tells me the diagnostics is having some issue somewhere that I'll have to track down. Whatever it is, is causing bogus errors when I try to check I believe the issue is some conflict with a bunch of stuff loaded into a shell that I have to program with. I did a quick prototype and it works fine. Note that this method will give you the item number in the list of checked items, not the overall list. Normally we don't use functions when the direct method is more exact and easier for other to understand when using the code. To determine checked items in a CheckedListBox control Iterate through the CheckedItems collection, starting at 0 since the collection is zero-based.

If you really think you need a function then this is how to do that. #region - įoreach( $item in $CheckedListBox. I even copy examples from forums to verify, and they fail.Īgain, in another area I have code to uncheck all items, and check the one item selected, with no problems. I have looked around, and no-one has see this issue. Is there some weird setting I need to have set or something, or a new PS version. The $false one has no problem with indexes, but the $true one throws an exception. This is such a simple operation, I have been using it since C# beta 1 and it works in VS, so I'm seeing it as a bug. I am able to manually set it to $false, or (1.0), but for some reason I'm unable to check it with $true

'InvalidArgument=Value of '-1' is not valid for 'index' In another area in the same script, I uncheck and check checkboxes in the same checkbox with no problems using the same syntax, pretty simple, however.įor some reason when I try to check the check box I get a error message box.Įxception calling 'SetItemChecked' with '2' arguments(s) I'm getting an exception thrown in a PowerShell SetItemsChecked, trying to check the checkbox.
